The world expects the UN to take lead in large scale humanitarian relief operations in the world’s worst emergencies. NGOs rely on the UN to provide the structure and leadership to work in refugee camps. Partner NGOs work through the UNA USA Council of Organizations to complement the UN’s relief work. They coordinate their work with UN Organizations such as the UN High Commissioner for Refugees (UNHCR), the UN Children’s Fund (UNICEF), the World Health Organization (WHO), and the World Food Program (WFP).
